The specific color variations can be subtle, resulting in a unique appearance for each colony. This inherent variability is part of what makes each "Little Shop of Horrors" zoa colony special and collectible.
How to Care for "Little Shop of Horrors" Zoanthids
While many zoanthids are relatively low-maintenance, providing the right environment is crucial for the health and vibrancy of your "Little Shop of Horrors" zoas.
Water Parameters:
Maintaining stable water parameters is critical. These zoas thrive in water with:
- Temperature: 72-78°F (22-26°C)

- pH: 8.1-8.4
- Alkalinity: 8-11 dKH
